Achieving rich, deep shades in textile dyeing is an art, but maintaining their vibrancy and preventing color transfer, especially wet rubbing, is a significant technical challenge. Fabrics dyed in dark black, bright red, or deep turquoise blue are particularly susceptible to crocking. NINGBO INNO PHARMCHEM CO.,LTD. offers SM-2020, a specialized solution for deep color wet rubbing fastness improvement, designed to meet these demanding requirements.
SM-2020 is a unique waterborne polyurethane polycation compound that targets the specific needs of cellulose fibers dyed with direct, reactive, and sulfurized dyes. Its mechanism involves forming a durable film on the fiber surface and cross-linking with active groups, effectively locking in the dye. This process significantly enhances the wet rubbing fastness by 1-2 grades, often pushing results beyond 3 grades, ensuring that deep colors remain brilliant and resist transfer even after extensive use and washing.
For textile manufacturers, the ability to consistently produce high-quality, deep-colored fabrics with excellent fastness is crucial for market competitiveness. SM-2020 provides the reliability needed to confidently tackle these challenging shades. As a leading supplier for deep shade auxiliaries, NINGBO INNO PHARMCHEM CO.,LTD. understands the nuances of dark black dyeing fastness and similar intensive color applications.
Beyond its fastness-enhancing capabilities, SM-2020 is also an environmentally responsible choice. It is formulated to be free of APEO, formaldehyde, and heavy metals, aligning with stringent global eco-standards. This means you can achieve superior color durability for your dark and vivid textiles without compromising on sustainability. Moreover, it leaves the fabric with a soft hand feel and does not adversely affect sunlight fastness or the original shade.
Partner with NINGBO INNO PHARMCHEM CO.,LTD. to optimize your deep shade textile dyeing processes. With SM-2020, you can ensure your darkest and brightest colors achieve unparalleled fastness, meeting the highest expectations for quality and performance in the textile industry.
